State and local officials said they did their best to coordinate evacuations and rescues, but better cellphone service might help in future floods.

The visit by acting Administrator David Richardson is his first known trip to a disaster site since President Donald Trump made him FEMA’s top official.

Kerr County Judge Rob Kelly, the county’s top official, said during a county commissioners court meeting earlier Monday that local officials don’t know the exact number of how many visitors who traveled to the Guadalupe for the holiday weekend had been caught in the flood.

At a Wednesday morning press conference, Kerr County Sheriff Larry Leitha declined to answer a question about delayed emergency alerts, saying that an "after-action" would follow the search and rescue efforts. "Those questions are gonna be answered," he added.

KERR COUNTY, Texas — Kerr County leaders debated the issue of installing emergency sirens along the Guadalupe River nearly a decade ago, but one former official said there was pushback from some residents.

Residents say Kerr County’s use of CodeRED alerts was sporadic and inconsistent. Local officials have not answered questions about when and how they utilized the system, which has been in place since 2009.

It’s discouraging that during this time when we have such a loss of life, and so many people’s lives have turned upside down, that people are playing politics with this,” Noem told NBC's Kristen Welker.

A vigil for those who lost their lives in the flooding in the Texas Hill Country was held in Fort Worth on Monday.
